T-Mobile says "the Un-carrier never stops" in a blog post announcing its new pay-as-you-go plan, set for availability August 17th. The carrier, which recently became the top prepaid provider in the US, is looking to simplify pay-as-you-go with a flat $0.10 cost per message or minute. The plan will have a $3.00 monthly minimum, which would give customers 30 minutes of talk or thirty SMS messages.

T-Mobile will also offer daily or weekly LTE data passes, with a day pass (allotting 500MB) priced at $5.00 and a seven-day pass (allotting 1GB) running customers $10.

WhatsApp, the incredibly popular messaging service recently acquired by Facebook for 19 Instagrams dropped an update for Android users today, bringing the app up to version 2.11.186. The update brings to the Play Store features beta users have enjoyed since version 2.11.181 earlier this month.

Users who grab the update will enjoy new privacy settings for "last seen," profile photo, and status (allowing users to limit who can see each), a camera shortcut (a 1x1 widget for quick photo capture), and several other UI improvements.

Square, the service that makes "commerce easy for everyone," has just expanded its mobile payment/commerce service to Canada.

For those unaware, Square is an app/accessory that allows you to accept credit card payments anywhere from Android or iOS devices.

It has all the standard features you'd expect from an app of this sort (e.g. finding directions to a local Friday's, checking out the chain's menus, and placing orders); however, it also has one notably unique feature: the ability to pay your bill. Powered by a service called Tabbedout, Friday's app lets you create "tabs" of items you'd like to order, before paying the tab directly from your phone.

For millions of coffee drinkers, Starbucks is a sort of a daily Mecca - they can't imagine skipping even a day, and spending over $100 a month on liquid caffeinated pleasures is pretty much business as usual. Because of that, unofficial Starbucks apps that replace Starbuck's own Starbucks Cards on mobile devices quickly gained popularity.

According to news website TheStreet, Google may be finally relenting on the Google Checkout-only system currently employed in the Android Market by letting PayPal in on the action. This is a facility that users have demanded for some time, and the ubiquity and convenience of PayPal payment should be a nice incentive for people to buy apps if they have not done so before. TheStreet also speculates that this new payment option may be the final piece of the puzzle in the long-awaited Google Music project, allowing for seamless payment from your device or PC.
